BUMPER FOR LITTER-CARRIERS.

Application filed May 4, 1914. Serial No. 836,231.

To all whom it may concern:

Be it known that I, HERRICK 1V. OSTER- HOUT, a citizen of the United States, resid ing at- Valley Falls, in the county of Benssalaer, State of New York, have invented certain new and useful Improvements in Bumpers for Litter-Carriers; and I do hereby'cleclare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

, This invention relates to bumpers for littercarriers.

The object of the invention resides in the provision of a bumper of the type referred towhich can be readily secured to any track or. cable and which will efliciently absorb the momentum of a litter carrier so as to bring same to a stop without possible injury'to the bumper or the carrier. V

Vith the above and other objects in view the invention consistsin the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the'invention in detail reference will be had --to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a side elevation of a litter carrier bumper constructed in accordance with. the invention and showing same applied to a track; Fig. 2 a plan view of what is shown in Fi g. 1; Fig. 3, a perspective view of the base block of the bumper, and Fig. a perspective view of the movable elements of the bumper.

Referring to the drawings 10 indicates a litter carrier track and '11 a litter carrier mounted thereon in the usual and well known manner.

The improved bumper is shown as comprising a body portion 12 provided with a longitud nal groove :13 in its lower face. This body portion 12 is provided at each end with opposite lateral ears 14 and engaged through corresponding opposite ears 141 are U-shapedclamping members 15 whereby the body portion 12 may be securely attached to the track 10. Secured to and embracing the body portion 12 are U-shaped guide members 16 which extend across the upper side of the body portion and havev their armconnecting portions disposed in spaced relation to the upper side of'the body portion. Slidably mounted in the guide members 16 is a bar 17 one end of which terminates in a depending arm 18 and the other end in head 19 provided on its outer end with a rubber cushion 20. The arm '18 is connected to the adjacent end of the body portion 12 by a spring 21 which normally holds the head 19 in spaced relation to the body portion 12. Movement of the head 19 away from the body portion 12 is limited by means of a stop 22 formed on the bar 17 and engageable with the end of the body portion to which the spring 21 is attached.

Specification of Letters Patent. Patented]? 'eb. 15, 1916. e

In the use of the device it will be appar out that thelitter carrier 11 or more specifically the suspending wheels thereof will en.- gage the cushion '20 andthe momentum of the carrier will tension the spring 21 asja result of longitudinal movement of the bar .17. This operation will serve to absorb the momentum of the carrier and arrest the movement thereof. When this momentum is completely absorbed the spring 21 will operate to movethe bar 17 toits normal position, such movement being limited by engagement ofthe stop 22 with the body por tion 12.

What is claimed is A device of the class described having means for attachment to a fixed track. guide members carried by a body portion and embracing one side edge thereof. a bar slidably mounted 1n sald guide members for longitudinal movement and entirely supported upon the side edge of the body embraced by the guide members, a depending arm on one 7 end of said bar, a spring connecting said arm and body portion and yieldingly holding the bar against movement in one direcv tion, and a head on the other end of said bar provided with a yielding cushion on the outer end' thereof.

.In testimony whereof, I afiix my signa ture, in the presence of two witnesses.
